ts-dag-eth

A TypeScript implementation of the codecs for Ethereum IPLD types for use with multiformats.

Testing

After running yarn, npm install, or npm ci; run npm test or yarn test from the root repo to run all the unit tests referenced from test/index.ts

Usage

The top-level index contains a mapping that aggregates all the ethereum codecs:

import { codecs } from '@vulcanize/dag-eth/'
import { Transaction } from '@vulcanize/dag-eth/tx/src/interface'
import { Receipt } from '@vulcanize/dag-eth/rct/src/interface'
import { CodecCode } from 'multicodec'

const txName = 'eth-tx'
const rctName = 'eth-rct'
const txCode: CodecCode = 0x93
const rctCode: CodecCode = 0x95
const txCodec = codecs[txName]
const rctCodec = codecs[rctName]
const accessListTxNode: Transaction = txCodec.decode(accessListTxEnc)
const dynamicFeeRctNode: Receipt = rctCodec.decode(dyanamicFeeRctEnc)
const accessListTxNodeEnc = txCodec.encode(accessListTxNode)
const dynamicFeeRctNodeEnc = rctCodec.encode(dynamicFeeRctNode)

// accessListTxEnc == accessListTxNodeEnc
// dyanamicFeeRctEnc == dynamicFeeRctNodeEnc
// txCode == txCodec.code
// rctCode == rctCodec.code
// txName == txCodec.name
// rctName == rctCodec.name

Or, you can import the individual codec pkgs:

import { encode as txEncode, decode as txDecode } from '@vulcanize/dag-eth/tx/src/'
import { encode as rctEncode, decode as rctDecode } from '@vulcanize/dag-eth/rct/src'
import { Transaction } from '@vulcanize/dag-eth/tx/src/interface'
import { Receipt } from '@vulcanize/dag-eth/rct/src/interface'

const accessListTxNode: Transaction = txDecode(accessListTxEnc)
const dynamicFeeRctNode: Receipt = rctDecode(dyanamicFeeRctEnc)
const accessListTxNodeEnc = txEncode(accessListTxNode)
const dynamicFeeRctNodeEnc = rctEncode(dynamicFeeRctNode)

// accessListTxEnc == accessListTxNodeEnc
// dyanamicFeeRctEnc == dynamicFeeRctNodeEnc
